Blank lines caused by file reference in Php (UTF-8)

Reference files refer to include, require_once reference other files caused by the blank line, which is actually after you use notepad to edit the UTF-8 file, although you still save as UTF-8 format, however, the system will automatically add two bom tags to the file,... reference files refer to include, require_once reference other files caused by the blank line, which is actually after you use notepad to edit the UTF-8 file, although you still save as UTF-8 format, however, the system will automatically add two bom labels to the file, but ie can only ignore one, and the other is blank lines.

Solution: Do not use notepad to edit the UTF-8 file, use other tools, such as Dreamw, EmEditor, Visual Studio 2008 and other editing tools to edit the UTF-8 file and save.

After editing the two sites in Notepad, there is a blank line on the top. at first, I thought it was a css setting problem and the result was caused by bom marking.

There is another way. if you use a large number of files, we can use a php function to copy the following code to a php file and run it in the directory where the BOM header needs to be cleared, you can delete the first blank PHP line in batches. the code is as follows:

 ";} Else {$ dirname = $ basedir. "/". $ file; checkdir ($ dirname) ;}} closedir ($ dh) ;}} function checkBOM ($ filename) {global $ auto; $ contents = file_get_contents ($ filename ); $ charset [1] = substr ($ contents, 0, 1); $ charset [2] = substr ($ contents, 1, 1 ); $ charset [3] = substr ($ contents, 2, 1); if (ord ($ charset [1]) = 239 & ord ($ charset [2]) = 187 & ord ($ charset [3]) = 191) {if ($ auto = 1) {$ res T = substr ($ contents, 3); rewrite ($ filename, $ rest); return ("BOM found, automatically removed. ");} else {return (" BOM found. ") ;}} else return (" BOM Not Found. ");} function rewrite ($ filename, $ data) {$ filenum = fopen ($ filename," w "); flock ($ filenum, LOCK_EX); fwrite ($ filenum, $ data); fclose ($ filenum) ;}?>
